Are you talking about nvmem-cells, nvmem-cell-names bindings? Since
at24 is i2c driver, I can only think at it as a nvmem provider. Using these
bindings it will imply, as per my understanding about nvmem subsystem, that
this should also become a nvmem consumer. It looks a little strange to
me but I don't have deep knowledge about subsystem, correct me if I'm wrong.
Please let me know if you are talking about using these bindings and reading
them (just to get the offset passed in "reg" binding) by not passing the nvmem
APIs defined in nvmem core.

Thank you,
